Yowsa, muri! Anybody have comments on reversing the process found on xlr8yourmac? IOW, take the firm resource out of the Mac OSX SCSI card updater, put it in the Atto 1.4.4 updater's firm resource, and run the 1.4.4 updater? Goal is to replace the Atto firmware with Apple's, and perhaps get it to boot, as suggested by Tony's post on 5-Nov. I have successfully swapped the firm resources; they are different physical sizes but the Atto updater still launches and quits at least without problems. I don't have the nerve to hit selection "2" (yet). Any comments? Any comments at all? |

If this can help ... Atto tech support told me that 144 is the latest release compatible with old world macs ... I hadn't success in booting as well ... Did anybody try to install the card and the hd on a G4 and then install OsX? Maybe this could work. And maybe the card could become bootable ... Bye Maurizio |

Greg, No, I wasn't able to get either of the UL2D cards to boot into X on the 9500 because they both came with ATTO's firmware installed. However, I did get both of my ATTO ExpressPCI Pro PSC cards to boot into X on the 9500 because they came with Apple's OEM firmware. I then made the huge mistake of changing the firmware on my first PSC card to ATTO's 1.6.6 at which point the PSC card would no longer boot into X. I ended up buying another PSC card with Apple's OEM firmware installed and left it intact. This is the only card that will boot X on the 9500. The problem with ATTO's firmware is isolated to booting into X on an unsupported machine. These cards and their attached drives will work properly AFTER the machine is booted using an Apple OEM card. And they will boot fine in OS 9 and will boot fine into X on supported machines. I have this theory that the problem with the ATTO firmware is related to the XPF extension(s) required for booting. Ryan had previously noted that XPF wouldn't boot from a drive using FWB's driver and I certainly confirmed that statement. On the surface, it seems that XPF's boot extensions expect to find Apple OEM firmware and an Apple (or Intech) disk driver at boot time. I know that Ryan has stated that the boot problem was not related to XPF, but the results of my tests aren't very clear in this area. I can boot into Jaguar on my Sawtooth AGP G4 using any of the ATTO PSC or UL2D cards with the ATTO firmware and formatted with the FWB driver. Any of these cards will boot into OS 9 on the 9500 without problems. And Jaguar indeed recognizes the ATTO cards and disks AFTER booting from another card with Apple's OEM firmware. The only thing that can explain the difference is that we're using XPF to boot the unsupported machines. I've never tried using Sonnet's boot utility in place of XPF - maybe someone else could run that experiment. As far as reverting back to the Apple OEM firmware, Ben Ralston thought it might be possible to modify his utility to accomplish this. But neither he nor I were brave enough to try it on our PSC cards and I doubt that his utility would work for the UL2D cards anyway. The only possible solution to this problem is if Ryan could force the X bootloader to recognize non-Apple firmware in our ATTO cards. I don't know if this is even possible due to the early timing of the problem. I was hoping that Ryan would eventually look into this, but I realize he's busy squashing other problems. |

The Atto UL2D boots fine into OX X on my 8500. I don't think I was able to do it directly with Xpostfacto. I had a copy of OS X installed on another drive that was on my internal SCSI buss and set the drive that's on my Atto card as the start up disk. I have the current version of the firmware. I installed 10.2 on the new drive by putting the drive in another machine I have that has an Atto PSC card and installing it there. I contacted Atto about updating the firmware but they say that they are no longer developing for that card since it was discontinued before OS X shipped. |

Tony - so you were able to boot OSX from your UL2D on a 9500 with the original Apple OEM firmware? Any thoughts on how to restore the Apple firmware? |

Frankly mjoecups358, and everyone else here, I'd say it's a lot more than shakey. I doubt there is anyone here with their head in the sand. I mean, just look at what we're trying to accomplish. OTOH, OWC needs to put a great big fat disclaimer on that card. Meanwhile, I've tracked down the source for this card in the current Linux/PPC kernel. The UL2D *does* boot my same box in Linux. So even if it's a firmware issue, there *should* be a workaround. I can do C, but I am no kernel programmer or driver writer :-/ |

I'm bummed this card isn't bootable in OSX. I had counted on it since my older Express PCI PSC card boots fine, and I had heard that ATTO's in general worked with OSX. Also it seems a little shakey that OWC advertises this card as OSX compatible, when in fact it will not boot under Xpostfacto. On the other hand, my card which came with 1.43f firmware, is visible in OSX and works as long as you don't need it to boot from. Marty |

This is the same error that I was getting with the ATTO ExpressPCI Pro card after I upgraded the firmware to 1.6.x. I tested two of these cards and both would boot OS X as long as Apple's OEM firmware was installed. But ATTO's firmware gives the "can't open" error. The odd thing is that these ATTO cards work just fine with the 1.6.x firmware on supported machines. I have two UL2D cards with the 1.6.4 firmware in my Sawtooth machine and they work perfectly. Neither card will work in my PowerMac 9500. My guess is that Apple's Openfirmware works correctly on supported machines but less than perfect on unsupported machines. Ryan's extensions should correct for the differences but I think something's still missing. |

I've tried a forced restart at the "can't OPEN" error with no success. PTP200(xlr8 g3400,atto ul2d firmware 1.44,atlas 10kII) - would love to hear from someone successfully booting into 10.x with XPost and an ATTO UL2D. |

I'm not sure--I suppose that I should try it myself and see what I can figure out. The other threads are indicating a "can't OPEN" message, which is what you would expect if the card was just not bootable in Mac OS X. But that would surprise me, as most of the Atto cards do work OK. One thing you could try is doing a forced restart as the "can't OPEN" messages are being displayed. For some reason, a warm start sometimes succeeds where a cold start fails. It seems to have something to do with the way in which drives are instructed to spin up at boot time. (Sometimes adjusting the 'Disable Unit Attention' jumper on the drive helps). |
